 ## Security considerations
 For security reasons, a random password and an SSH key-pair are auto-generated per instance.
 This means that each instance has a different password and a different authorized SSH key.
+They are stored in the `tfstate` so execute a `terraform state list` and then show the resource you need
+by using `terraform state show ···`
 
 When the `terraform apply` is complete, all the SSH private key files are exported in order 
 to allow you to access or manage them.
 
-There is a special folder called `external-ssh-keys` which was created for the special case that several
-well-known SSH keys must be authorized in all the instances at the same time.
+There is a special directory located in `modules/workload/external-ssh-keys`. 
+This was created for the special case that several well-known SSH keys must be authorized 
+in all the instances at the same time.
 This can be risky and must be used under your own responsibility. If you need it, place some `.pub` key files
 inside, and they will be directly configured and authorized in all the instances.
